The development of the programmable controller

In 1969, the United States, digital equipment corporation ( 12月) Developed the first programmable controller for gm's production line, replace the relay control system on the production line, marked a new epoch in industrial control. In 1971, Japan began to produce programmable controller, Germany, Britain, France and other countries have developed a suitable for their own programmable controller, and promote the use. In 1974, our country also began to the programmable controller in the development and production. Early programmable controller is to replace the relay - Contactor control system designed for on-off control, has the logic operation, such as a sequential control, timing, counting function called PLC (programmable logic controller 可编程逻辑控制器) 。 With microelectronics technology, computer technology and the rapid development of modern digital control technology, by the end of the 80 s, the PLC technology has been very mature, and from the switch quantity logic control extended to computer numerical control ( CNC) And other fields. In recent years, the production of PLC controller in processing speed and control function, communication ability, etc all have new breakthrough, and to the integration of electrical control, instrument control and computer control direction, price performance ratio improve, become one of the pillars of the industrial automation. At this time of the function of the programmable controller is not limited to logic operation, with the continuous analog processing, high-speed counting and network communication, remote input and output, and other functions. The international electrotechnical commission ( IEC) The programmable logic controller renamed the programmable controller (PC), 可编程序控制器) 。 Due to the later found its abbreviations and personal computer ( 个人电脑) The same, so again continue to use PLC controller. At present in the world's advanced industrial countries PLC has become the standard of industrial control equipment, its application covers almost all industrial enterprises. PLC controller technology has become a trend in today's world, become the pillars of industrial automation, PLC technology, robot, computer aided design and manufacturing) One of the.
